However, because of the lack of cultural knowledge of the target language, many cross-cultural contacts turn out to be frustrating or even a failure. Therefore, to guarantee an effective intercultural communication, a lot of knowledge about target culture is needed; besides, people should have a good command of different cultures and should fully understand the cultural differences in intercultural communication. So it is important and of great necessity to take culture into consideration in FLT. But how to acquire cultural knowledge effectively always exists as a problem. In this thesis, the author attempts to solve the problem by using schema theory. Schema is a sort of background knowledge stored in a person's mind in order to perceive and understand the world. Usually if a person possesses more foreign cultural schemata, he or she will behave appropriately in cross-cultural communication. Therefore, the task left is how to help students build up their cultural schemata about a foreign language.展开更多

It was honored by World Native Culture Fund as One of the Eighteen Ecological and Cultural Conservations in the World. The prototypical ethnic culture of Southeast of Guizhou, as a stable life-style and economic culture type of the local people, came into being in the process of the local minorities＇ communicating, blending and struggling against the natural environment in the long course of history. It could be seen from this research that there were our preliminary research that there are quite abundant resources in Southeast of Guizhou in terms of prototypical ethnic cultures and genetic diversity of glutinous rice. A full reflection of the culture of Glutinous Rice could be seen in the local minority people＇s daily life, production, custom, religious belief, etc. These showed that the formation and great vitality of the genetic diversity of glutinous rice was not only determined by the diversity of local prototypical ethnic cultures but also to its own biotic condition and its adaptation to natural ecology. It was showed that prototypical ethnic cultures had positive impact on the conservation and utilization of Glutinous Rice diversity.展开更多

文摘Cell cultured meat has been extensively studied as an environmentally friendly,energy-saving and more effective technology.However,there are many technical bottlenecks,especially the regulatory mechanism and manufacturing method of in vitro myogenesis.Based on an edible modified silk protein scaffold,with 3D culturing,in situ differentiated and transcriptome analysis,this study describes novel scaffolds and fabrication methods for cell cultured meat.The results showed that the effective space and utilization efficiency for cell culture of the scaffold is 26–1000 that of the traditional culture dish;it could form a tissue-like structure.Transcriptomics revealed the regulatory pathways and key factors of different cycles.It clarifies that the multi-cycle process of myoblast myogenesis in vitro is different from the single feedback regulation in vivo.More importantly,a novel scaffold-based cell cultured meat manufacturing method was developed,further develop a new tissue culture solution that is different from existing cell culture meat production.For manufacturing processes,it provides a new cell culture meat technology system,provides a theoretical basis for the regulation of cell proliferation and muscle growth,and lays the technical foundation for in situ tissue culture of cell cultured meat in vitro.

文摘This study focuses on the deepening paths of ideological and political construction of professional courses in higher vocational colleges,taking the layout design course of the digital media technology major as the research object,and explores the integration mechanism of excellent traditional Chinese culture and professional teaching.The curriculum’s ideological and political reform is advanced through three major measures:Reconstructing the role of teachers,innovating teaching methods,and building a cultural infiltration system.Combined with the three-dimensional assessment mechanism of“professional+culture+value”and the transformation of teaching achievements into competitions,it breaks through the limitations of traditional skill training and systematically solves the problems of formalization tendency and insufficient value guidance existing in the practice of curriculum ideology and politics.It responds to the era proposition of“promoting the creative transformation of excellent traditional Chinese culture,”and provides an operable solution for higher vocational colleges to break the predicament of“emphasizing skills while neglecting culture.”
文摘Ideological and political education is crucial for implementing the fundamental task of fostering virtue through education.Colleges and universities,as the main front,shoulder the important responsibility of cultivating talent.At present,with the exchange and collision of Eastern and Western cultures,it is necessary to accelerate the effective integration of excellent traditional Chinese culture with ideological and political education in colleges and universities.Firstly,based on college classrooms,excavate the ideological and political elements of traditional culture and integrate them into courses;Secondly,carry out practical activities,such as traditional culture themed lectures and experience activities,to enhance students’cultural identity;Thirdly,build a“Internet+”new system,use new media platforms to spread traditional culture,and strengthen the leading role of ideological and political education,to help build a cultural power.
文摘With the coming of the information era and the flaming of the international communication, the English language has already made itself a very important and universally used language. However, because of the lack of cultural knowledge of the target language, many cross-cultural contacts turn out to be frustrating or even a failure. Therefore, to guarantee an effective intercultural communication, a lot of knowledge about target culture is needed; besides, people should have a good command of different cultures and should fully understand the cultural differences in intercultural communication. So it is important and of great necessity to take culture into consideration in FLT. But how to acquire cultural knowledge effectively always exists as a problem. In this thesis, the author attempts to solve the problem by using schema theory. Schema is a sort of background knowledge stored in a person's mind in order to perceive and understand the world. Usually if a person possesses more foreign cultural schemata, he or she will behave appropriately in cross-cultural communication. Therefore, the task left is how to help students build up their cultural schemata about a foreign language.

文摘There were quite abundant prototypical ethnic cultures and plant diversity in Qiandongnan （ Southeast of Guizhou） ,where the primitive natural ecology was also perfectly conserved. It was honored by World Native Culture Fund as One of the Eighteen Ecological and Cultural Conservations in the World. The prototypical ethnic culture of Southeast of Guizhou, as a stable life-style and economic culture type of the local people, came into being in the process of the local minorities＇ communicating, blending and struggling against the natural environment in the long course of history. It could be seen from this research that there were our preliminary research that there are quite abundant resources in Southeast of Guizhou in terms of prototypical ethnic cultures and genetic diversity of glutinous rice. A full reflection of the culture of Glutinous Rice could be seen in the local minority people＇s daily life, production, custom, religious belief, etc. These showed that the formation and great vitality of the genetic diversity of glutinous rice was not only determined by the diversity of local prototypical ethnic cultures but also to its own biotic condition and its adaptation to natural ecology. It was showed that prototypical ethnic cultures had positive impact on the conservation and utilization of Glutinous Rice diversity.
